“…Six patients had both transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE). An incremental diagnostic value of TEE has been described in two (Patients 3 and 4) 8,11 . In Patient 3, a preoperative TTE failed to diagnose PMV but intraoperative TEE diagnosed a PMV with a single papillary muscle 8 .…”

“…An apical long‐axis view showed a typical parachute deformity of the mitral valve with a normal opening and common attachment of all the chordae. The chordae were elongated which was atypical—typically the chordae are shortened and thickened 11 . Two patients (Patients 1 and 2) 6,7 had the diagnosis of PMV made at autopsy.…”

“…Among adult PMV with an associated congenital cardiac lesion (Patients 4, 5, 6 and 9), atrial fibrillation was the presenting feature in two patients: one had an associated congenital double orifice mitral stenosis, bicuspid aortic valve, and status post coarctation repair (Patient 4) 11 ; the second (Patient 5) 12 with mild obstructive lesions in both mitral and aortic valves (bicuspid aortic valve) and insignificant coarctation of aorta. One patient (Patient 9), 13 with double orifice, single ventricle, and pulmonary stenosis presented with progressive shortness of breath due to congestive heart failure and one patient with a subaortic VSD (Patient 6), 14 presented with an asymptomatic holo‐systolic murmur.…”

Parachute mitral valve (PMV) is a rare congenital anomaly of the mitral valve apparatus seen in infants and young children. In most instances PMV is associated with other congenital anomalies of the heart, in particular obstructive lesions of the mitral inflow (mitral valve ring) and left ventricular outflow tract (subaortic stenosis), and coarctation of aorta and is referred to as Shone's complex or Shone's anomaly. PMV may also occur as an isolated lesion or in association with other congenital cardiac anomalies. Not much is known about PMV in adults as an isolated anomaly or in association with other congenital cardiac anomalies. We reviewed the literature to identify cases of PMV (isolated or associated with other lesions) in adults, to address prevalence, clinical presentation, diagnosis, treatment, and outcome of such patients. (Echocardiography 2010;27:581-586).

“…Previously reported cases of DOMV had single or multiple papillary muscles. 3,4 However, previous echocardiography techniques had lower resolution; therefore, an accurate papillary muscle count could be determined only by open heart surgery or autopsy. In the present case, we could identify 2 complete sets of mitral valves including 4 papillary muscles and related structures by using a multimodal approach of TTE, heart dynamic computed tomography scan, and TEE.…”

“…In addition, intraoperative transesophageal echocardiography was superior in defining the anatomy of the subvalvular apparatus with prospective identification of single papillary muscle that supported both mitral valve orifices with parachute phenomenon. 5) From the aspect of long-term prognosis, it is wellknown that mitral valvuloplasty is superior to mitral valve replacement. Zhou et al reported that thirty-day mortality was lower after mitral valvuloplasty compared to after mitral valve replacement.…”

A 65-year-old woman with exercise-related dyspnea was admitted to our hospital. Transthoracic echocardiography demonstrated a large anomalous papillary muscle that originated from the posterior wall of the left ventricle and severe mitral valve regurgitation in systole. Cleft suture, 5-0 polytetrafluoroethylene sutures from a single papillary muscle to the anterior commissure leaflet (AC), 5-0 polypropylene sutures between AC and A1, and between A1 and A2, the double-orifice technique, and ring plasty with 32-mm semi-rigid ring was performed. Postoperative echocardiography showed an improvement in severe mitral valve regurgitation. At the 2-month follow-up, the patient was in good health. In the present case, the elderly patient with an isolated parachute mitral valve but without any other cardiac anomaly and presenting with mitral valve regurgitation is extremely rare. This case of mitral valvuloplasty for a parachute mitral valve with a single papillary muscle in an elderly woman has not been reported before.Keywords: parachute mitral valve, single papillary muscle, mitral valve regurgitation, mitral valve plasty Case ReportA 65-year-old woman who had exercise-related dyspnea was admitted to our hospital for evaluation. She had been asymptomatic before presentation. On physical examination, there was a grade 4/6 holosystolic regurgitant murmur audible throughout the precordium. The peripheral pulses were normal, and the rest of her examination was unremarkable. Anteroposterior chest X-ray demonstrated no cardiomegaly showed a sinus rhythm with a rate of 66/min, and complete right bundle branch block. A two-dimensional and color Doppler echocardiogram was performed. It demonstrated a large anomalous papillary muscle that originated from the posterior wall of the left ventricle with a dilated left atrium and left ventricle, and a cleft in the posterior leaflet of the mitral valve (Fig. 1a). Color Doppler showed severe mitral valve regurgitation in systole (Fig. 1b). Pulse-Doppler recording of transmitral flow from the left ventricle apex demonstrated no features of mitral valve stenosis (Fig. 1c). Cardiac catheterization was performed which confirmed the diagnosis and demonstrated hyperkinetic pulmonary artery
